tarantoolctl is a utility for administering Tarantool instances, checkpoint files and modules. It is shipped and installed as part of Tarantool distribution.

See also tarantoolctl usage examples in Server administration section.

Command format

tarantoolctl COMMAND NAME [URI] [FILE] [OPTIONS..]

where:

COMMAND is one of the following: start, stop, status, restart, logrotate, check, enter, eval, connect, cat, play, rocks.
NAME is the name of an instance file or a module.
FILE is the path to some file (.lua, .xlog or .snap).
URI is the URI of some Tarantool instance.
OPTIONS are options taken by some tarantoolctl commands.

Commands for managing Tarantool instances

tarantoolctl start NAME

Start a Tarantool instance.

Additionally, this command sets the TARANTOOLCTL environment variable to ‘true’, to mark that the instance was started by tarantoolctl.

Note

tarantoolctl works for instances without box.cfg{} called or with delayed box.cfg{} call.

For example, this can be used to manage instances which receive configuration from an external server. For such instances, tarantoolctl start goes to background when box.cfg{} is called, so it will wait until options for box.cfg are received. However this is not the case for daemon management systems like systemd, as they handle backgrounding on their side.

tarantoolctl stop NAME

Stop a Tarantool instance.

tarantoolctl status NAME

Show an instance’s status (started/stopped). If pid file exists and an alive control socket exists, the return code is 0. Otherwise, the return code is not 0.

Reports typical problems to stderr (e.g. pid file exists and control socket doesn’t).

tarantoolctl restart NAME

Stop and start a Tarantool instance.

Additionally, this command sets the TARANTOOL_RESTARTED environment variable to ‘true’, to mark that the instance was restarted by tarantoolctl.

tarantoolctl logrotate NAME

Rotate logs of a started Tarantool instance. Works only if logging-into-file is enabled in the instance file. Pipe/syslog make no effect.

tarantoolctl check NAME

Check an instance file for syntax errors.

tarantoolctl enter NAME

Enter an instance’s interactive Lua console.

tarantoolctl eval NAME FILE

Evaluate a local Lua file on a running Tarantool instance.

tarantoolctl connect URI

Connect to a Tarantool instance on an admin-console port. Supports both TCP/Unix sockets.

Commands for managing checkpoint files

tarantoolctl cat FILE.. [--space=space_no ..] [--show-system] [--from=from_lsn] [--to=to_lsn] [--replica=replica_id ..]: Print into stdout the contents of .snap/.xlog files.
tarantoolctl play URI FILE.. [--space=space_no ..] [--show-system] [--from=from_lsn] [--to=to_lsn] [--replica=replica_id ..]: Play the contents of .snap/.xlog files to another Tarantool instance.

Supported options:

--space=space_no to filter the output by space number. May be passed more than once.
--show-system to show the contents of system spaces.
--from=from_lsn to show operations starting from the given lsn.
--to=to_lsn to show operations ending with the given lsn.
--replica=replica_id to filter the output by replica id. May be passed more than once.

Commands for managing Tarantool modules

tarantoolctl rocks install NAME

Install a module in the current directory.

tarantoolctl rocks remove NAME

Remove a module.

tarantoolctl rocks show NAME

Show information about an installed module.

tarantoolctl rocks search NAME

Search the repository for modules.

tarantoolctl rocks list

List all installed modules.

tarantoolctl rocks pack {<rockspec> | <name> [<version>]}

Create a rock by packing sources or binaries.

As an argument, you can specify:

a .rockspec file to create a source rock containing the module’s sources, or
the name of an installed module (and its version if there are more than one) to create a binary rock containing the compiled module.

tarantoolctl rocks unpack {<rock_file> | <rockspec> | <name> [version]}

Unpack the contents of a rock into a new directory under the current one.
